河北省野生树种的木材直接利用价值情况是判断该树种是否为珍贵树种及珍稀濒危树种必不可少的内容,对其进行系统地评价对野生植物在木材应用领域进一步开发利用具有重要的现实意义。编程设计出层次分析法(AHP)模块,通过该模块支持的软件页面录入数值,确定木材直接利用价值的各级指标权重值;利用河北省林木种质资源普查数据,结合知识工程(KBE)技术,获得参评野生树种对应的木材直接利用价值的具体指标权重,获得综合权重值并进行聚类分析,总结出分为4级的木材直接利用价值的河北省野生树种。
The direct timber utilization value of wild tree species in Hebei Province is an indispensable part of judging whether the tree species are valuable species and rare and endangered tree species. It is of great practical significance to systematically evaluate the further development and utilization of wild plants in wood application field. (AHP) module is designed and programmed, the numerical values are input through the software pages supported by this module, and the index weight value of direct use value of wood is determined. Based on the census data of forest germplasm resources in Hebei Province and the combination of knowledge engineering (KBE) , Obtain the specific index weight of direct timber value corresponding to the wild tree species, obtain the comprehensive weight value and cluster analysis, and sum up the wild tree species of Hebei Province which is divided into four grades of direct timber use value.
